WILLIAM M. SCOTT, OF CENTRAL, SOUTH CAROLINA.

' STEEL CROSS-TIE.

Application filed June 6, 1912.

To all whom it may concern:

Be it known that I, WVILLIAM M. Soon, a citizen of the United States, residing at Central, in the county of Pickens and State of South Carolina, have invented certain new and useful Improvements in Steel Cross- Ties; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in steel cross ties.

The object of the invention is to provide a simple, economical, and durable, tie, and one which by reason of its shape will once it is embedded in the ballast, be prevented from twisting or turning out of its set position.

The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims.

In the drawings: Figure 1 is a plan view. Fig. 2 is a longitudinal section on the line 2-2, of Fig. 1. Fig. 3 is a detail vertical section on the line 33, of Fig. 2. Fig. 4 is a plan View, parts broken away and illustrating a slight modification. Fig. 5 is a detail section on the line 5-5, of Fig. 4:. Fig. 6 is a perspective view of one of the tie sections. Fig. 7 is a similar View of the companion tie sections. Fig. 8 is a detail view of one of the chairs. Fig. 9 is an inverted view of the same.

My improved tie comprises two sections 1 and 2. The section 1 is U-shape in cross section from a point some distance from the center of the tie, to the outer free end, as shown at 3. The inner portion of the section 1, is inwardly beveled at 4, and terminates in a prong 5, and is formed with two wedge seats 6. Section 2, is U-shape in cross section throughout its entire length, and at its inner end its outer vertical walls are inwardly beveled, as at 7, and is provided with two wedge seats 8.

The prong 5, is placed in the inner channeled end of the section 2, and two oppositely disposed wedges 9, are passed through the wedge seats 6 and 8, and are adjusted to regulate the gage of the track. After pecification of Letters Patent.

Serial No. 702,049.

the wedges have been adjusted, cotter pins, or other locking devices 10, are passed through perforations appropriately located in the wedges. v

Near the outer ends of sections 1 and 2, are riveted or otherwise fastened rail chairs 1111. Each chair is of inverted U form in cross section and fits snugly in the channeled portion of the section. The outer upper end portion of the chair is somewhat thicker than the remaining portion, as shown at 12, and on the inner edge of the thickened portion is an undercut flange 13, which forms a seat for one of the side flanges of a rail. The thickened portion is designed for the purpose of resisting the outward thrust of the rail, and it also serves to hold the rail in position.

The upper end portions of the sections 1 and 2 are on a level with the thickened portions 12, and in alinement with the flanges 13, are abutting flanges 14., so that the outer flanges of the rails are held by both the chairs and the tie sections.

The rails 15 are seated on the chairs and the tie sections as shown, and are secured by spikes 16. The spikes may be driven through openings 17 formed in the sides of the chairs and the bottom of the sections, as shown in Figs. 1 to 3, or the openings may beformed in the inner surfaces of the walls of the sections and the outer walls of the chairs, as shown in Figs. 5 and 6.

The openings 17 are plugged with wood, indicated at 20, so that when the spikes are driven in place, they will be tightly held in position.

In operation, the chairs are fitted in the channel portions of the sections 1 and 2 and riveted in place. The flanges 13 of the chairs are in alinement with the abutments 14:, so as to form a substantial abutting surface for the outer rail flanges. The rails are fitted on the chairs, and are then spiked down, after which the wedges 99, are driven in the seats. The wedges are first preliminarily driven in their seats until the track gage is determined. Then by driving first one and then the other, the exact distance between the rails is obtained. The proper gage having been obtained, the cotter pins are inserted and the operation is completed.

Because of the tapering and channel formation of the sections 1 and 2, the ballast will hold the tie in fixed position, and liability of any lateral or end movement is practically impossible.

If desired, a copper, or other plate, 21, may be interposed between the rails and the chairs, when the tie, is used on electric roads.

What I claim is:

1. In a met-a1 tie, the combination of two sections, each of which is formed with a channel and is tapered on the sides at the inner end portion, a prong extending from: one of the sections and fitting in the channel portion of the other section, the tongue and the side Walls of the section receiving the same having wedge seats which taper in opposite directions, and wedges driven in the wedge seats, the side Walls of the outer ends of the sections having abutments, U chairs secured in the channel portions of the sections and fastened to the latter, each chair having a flange which is in alinement with the abutments on the section and 1 against which a rail bears, the sections and I,

, for supporting and secur ng rails,

In testimony whereof'I have signed my chairs having spike openings.

2. In a metal railroad tie, the combination of two channel sections one of said sections 1 having a tongue which fits in the channel of the adjacent section, means for securing the two sections together at substantially the central portions thereof, and U-shape chairs in the channel portions of the sections, each chair having a thickened portion at its outer upper end and formed with a flange, the chairs and the sections having spike openings with wood plugs therein.

3. In a metal rail road tie, the combination of a body portion formed with depressions and having inwardly tapering side walls, the ends of the body portions having abutnients, U-shape chairs fastened in the depressions in the body portion, each chair having an enlargement at its outer end which forms a rail flange in alinement with the abutments on the body portion, the chairs and body portion having spike openin s.

f. In a rail road tie, the combination of two channel sections, one of which is formed with a central tongue which fits in the channel of the adjacent section, the tongue and the side walls of the section receiving said tongue havng horizontal oppositely inclined wedge seats, oppositely inclined wedges fitting in said Wedge seats to adjust the length of the tie, and means at the ends of the tie name to this specification in the presence of two subscribing witnesses.
